DESCRIPTION

The PA17 is a high voltage MOSFET power operational

amplifier that extends the performance limits of power ampli­fiers in slew rate and power bandwidth, while maintaining high
current and power dissipation ratings.

The PA17 is a highly flexible amplifier. The shutdown

feature allows ultra-low quiescent current for standby opera­tion or load protection by disabling the entire amplifier. Boost
voltage inputs allow the small signal portion of the amplifier to
operate at a higher voltage than the high current output stage.
The amplifier is then biased to achieve close linear swings to
the supply rails at high currents for extra efficient operation.
External compensation tailors performance to user needs. A
four wire sense technique allows current limiting without the
need to consider internal or external milliohm parasitic resis­tance in the output line.

NOTES 1. Unless otherwise noted: TC = 25°C. DC input specifications are ± value given. Power supply voltage is typical rating.

±VB= ±VS, Cc = 470pF, Rc=100Ω.

2. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation
to achieve high MTTF. For guidance, refer to the heatsink data sheet.

3. Rating applies if the output current alternates between both output transistors at a rate faster than 60 Hz.

4. The PA17 must be used with a heatsink or the quiescent power may drive the unit to junction temperatures higher than 150°C.

5. Parameter guaranteed but not tested.
